[Security Solution] Coverage Overview page: optimize rendering performance

[banderror]

Epic: https://github.com/elastic/security-team/issues/2905

Summary

Changing filters on the MITRE ATT&CK® Coverage page is quite slow and unresponsive.

For example, when you click on Expand cells, it takes ~2.7 seconds to re-render and paint the grid. The UI feels "frozen" during this time:

A similar situation is with changing the Installed rule status or Installed rule type filters, although it could be a bit faster in terms of rendering compared to expanding/collapsing cells.

The contribution of the internal/detection_engine/rules/_coverage_overview endpoint here is anything from 50ms to 250ms locally given 869 installed prebuilt rules.
